The articles in Computer Shopper were pretty much fairly low effort filler. Not that there weren’t tons of ads in things like PC Magazine but the articles/columns/reviews were of pretty good quality for the most part.
While the point of the articles was to keep it legally qualified as a "magazine" rather than a "catalog" (as postal rates then favored the former over the latter), there were some good things there. Don Lancaster wrote some amazing articles about Postscript and how you can write Postscript code to make figures rather than using a drawing program. And Stan Veit, who was editor of Computer Shopper for a time, wrote some good history articles about the early personal computer scene in the 1970s (Veit had opened in 1976 the first computer store in NYC, and one of the first in the USA as a whole)
Fair. I had forgotten about Don Lancaster, probably because that was never an area of particular interest. Mostly only bought Computer Shopper if I were building a PC or something like that.
